Lol, okay, I suppose that's a little harsh and not very accurate. But you have to understand, for me, I consider every game that involves falling squares/rectangles to be a Tetris ripoff.

As for the "matching different colors" twist on the Tetris formula, I prefer Dr. Robotnik's Mean Bean Machine. You actually had different opponents with different strategies, and their expressions would change based on how well you were doing. It was a better, more sophisticated game imo.
